NIAGHINE FOR FORMING COLLAR-BUTTONS.

SPECIFICATION forming' part of Letters Patent No. 782,309, dated February 14, 1905. i

' Application ned May 1904. serai No. 206,702.

T all whom, t may concern:

Be it known that I, EDWARD J. YALE, acitizen of the United States, residing at North Attleboro, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Machines for Formy ing Collar-Buttons, of which the'following is a specification, reference being had therein to the accompanying drawings.

My machine is adapted to form or spin cupshaped blanks into buttons, cartridges, and similar articles, and has for its ends the purposes commonly sought in thisclass of machines.

My invention consists in the novel construction and combination of parts hereinafter disclosed in the specification and illustrated-in the accompanying drawings, wherein- Figure 1 isa side elevation of the entire machine, showing the spindle and its bearings in vertical' central section; Fig. 2, a sectional elevation of the same on line m m of Fig. 1; Fig. 3, a front elevation of the roll-carriers and their base; Figs. 4, 5, and 6, a rear elevation, partial plan, and side elevation, respectively, of the same; Fig. 7, a longitudinal section of the same on line y y of Fig. 3; Fig. 8, a detail plan of the cam which operates the locking-pin; Fig. 9, an enlarged sec` tionaldetail of the holding-chuck, and Fig. 1Q an end viewof the chuck and clamping device. Y

Like reference-numerals indicate like parts throughout the views.

The 'framework of my machine may be of any form of construction suitable for carrying the several details of the mechanism. In the form thereofl herein shown it consists, essentially, of a bed 1, provided with a standard 2. Fixed upon the rear end ofkthese by screws 3 is a head-stock 4, provided with upright arms 5, in which are mounted bearings and 11 for a spinning-spindle 12. VSplined to the spindle is its driving-pulley 13. The spindle is provided with a longitudinallybored mandrel 14, whose interior is enlarged a portion of its length to accommodate the head of a slidable discharge-pin 15. This pin traverses the spindle and projects beyond the Secured upon rear extremity of the latter.

the end of the mandrel is an exteriorly-tapered split spring collar 16, intermediate which and the mandrel is placed the blank 17. A collar 18 slides upon the tapered springcollar 16. Upon a reduced portion of the head of the discharge-pin is a spiral spring 19, which normally tensions the pin rearwardly. Ball-bearings 2O facilitate the rotation ofthe spindle. A nut 6 in the bearing 10 takes up the thrust of the spindle.

The blank is engaged and released by the reciprocation of the collar 18 upon the spring 16. The mechanism for electing this is the following: A bell-crank lever 22 is mounted in a bracket 23 upon the bed 1. From one arm of the lever depends a rod 24, engaging a pedal-bar 25fulcrumedin a bearing 7.

The other arrn of the bell-crank lever contacts with the rear extremity of a horizontally-disposed bar 26, to whose forward end is connected a lever 27, fulcrumed intermediate its length to a bracket 28 upon the head-stock 4, and whose opposite end engages the collar 18. The bar 26 is tensioned by a spring 29, retained intermediate a nut 30 and the standard 2. A second nut 31 upon the threaded bar 26, upon the opposite side of the Wall 0f the standard, furnishes an adjustable stop to the rearward travel of said bar. The tension on this bar is regulated by the nut 30.

The arm 5 of the head-stock is upwardly and rearwardly extended and has pivoted to its extremity a vertical bar 32, whose lower extremity is connected by a chain 3 3 to the f vand 38,engaging gears 39 and 40,- respectively,

mounted on pins 41 andv 42 inthe front face of the carriage-base. To the hub 39 of gear 39 is xed a hand-lever 43. Mountedlongitudinally in the carriers 35 and 36 are shafts 44 and 45, having, respectively, on one end disks 46 and 47, which carry rolls in pairs 48 48, 49 49', 50 50', 51 51. Each successive 100 pair of rolls varies in shape and diameter from its predecessor. Upon the `opposite ends of the shafts 44 and 45 are fastened gears 52 and 53 by means of collars 54 and 55. Fixed to the extremities of the rear end of the carriage-- base 34 are guide-blocks 57 and 58, in which rest the ends of a bar 56, which is upwardly tensioned by spiral springs 59 60 and has its upward tendency limited by flat spring-catches 61 and 62, Xed to the guide-blocks. Mounted in the bar 56 are two racks 63 64, adapted to engage in certain positions with gears 52 and 53, respectively. Also fixed to the bar and intermediate the racks is secured a cam-block 65 with beveled ends 66 67. Secured to the carriers 35 36 are angle-bars 68 69, in which are fastened by adj listing-screws 68 69 pins 70 71,in alinement with the top of springcatches 61 62. Mounted in the carriers are spring-actuated locking-pins 72 73, adapted to enter holes 74 in the roll-disks 46 47. Depending' from the locking-pins are pins 7576, carrying cam-rolls 77 78, which engage with a cam 79, 'Xed transverselyv upon the carrierbase 34, as shown in Fig. 8.

The operation of my machine is as follows: The pedal 25 isdepressed, whereby the chuckcollar 18 is retracted, as already described,

and the blank inserted intermediate the man drel 14 and springs 16 in the manner indicated in Fig. 9. The pedal is then released and the action of spring 29 forces the collar 18 forward, thereby clamping the blank tothe mandrel. To furnish working space pending the insertion of the blanks the roll-carriers 35 36 are separated by elevating the hand-lever 43, which rotates the intermeshing gears 39 40. When the carriers have reached the eXtreme of their outward travel, the pins 70 71 contact with and force outwardly the hooked eX- tremities of spring-catches 62 61, thereby releasing bar 56, which is forced upwardly by springs 60 59, and allowing racks 63 64 to engage With gears 52 and 53, respectively. When the blank has been clamped to the mandrel, where it is rotated at great speed by the spindle-pulley 13, the forming operation is performed as follows: The lever-handle 43 is depressed and the carriers 35 36 approach each other. The roll-disks 46 47 revolve, actuated by the gears 52 53, meshing with racks 63 64, thus bringing into proper adjacent relation the roll-couplets, assumed in this instance as 48 48. The length of the racks is such that the roll-disks are revolved ninety degrees. Immediately this has occurred the spring-actuated locking-pins 72 73 enter holes 74 in the roll-disks and lock thelatter against further rotation. The carriers 35 36 continue their advance, and as they approach each other collars 54 55 contact with the beveled surfaces 66 67 on block 65, forcing the bar 56 downward and causing the latter to be locked down by the spring-catches 61 62. The pair of rolls 48 are now in contact with the revolving blank, which is spun and partially reduced in cross-section in accordance with the cross-sectional contour of the rolls. The lever-handle is again elevated, the rollcarriers drawn apart, the locking-pins 72 73 withdrawn from disks 47 46 by the action of cam 79 upon the pins 75 76, and the pins 70 71 disengage the spring-catches from the ends of the bar 56, 'thus allowing the gears 52 53 to mesh with racks 63 64. The lever-handle 43 is again depressed, advancing the carriages and rotating' the roll-disks ninety degrees, thus bringing the pair of rolls 49 49l into juxtaposition and in contact with the blank to further reduce and shape the latter. The carriers are again retracted and the above operation repeated until the entire roll series, including 51 51', have acted upon the blank. Thereupon the pedal 25 is again depressed, throwing back thc collar 18 to release the blank 17 and advancing the pin 15 to discharge the finished product from the chuck.

It will be noted that the pins 71 are capable of adjustment to the end `that the bar 56 may be released at a certain time, thereby enabling the gears 52 53 to mesh with their respective racks in such position that the rolldisks may be revolved exactly ninety degrees and in proper relation to each other.
